3 Claims.

This invention relates to new and useful improvements in a combination headlight and fog light for automobiles.

Heretofore, it has been discovered that a frosted amber bulb or lamp is better suited for use in fogs than the usual white light lamps. For this reason it has become customary to sell fog lamps as extra equipment. This invention proposes the construction of a head lamp which contains the usual clear glass bulb to be used in ordinary weather, and also contains an amber frosted bulb to be used during fogs. The advantage of the construction, in accordance with this invention resides in the fact that one head lamp is suflicient for use in all kinds of weather instead of the two now required.

The dominant advantage of the new construction is that car manufacturers can place the new head lamps upon cars as standard equipment at practically no additional cost and supply a head lamp which may be used in fogs as well as in clear and other weather.

For further comprehension of this invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a sectional view of a head lamp constructed in accordance with this invention.

Fig. 2 is a sectional View similar to Fig. 1 but illustrating a modified form of the head lamp embodying the same invention.

Fig. 3 is a sectional view of the head lamp shown in Fig. 2 with the parts in a dilferent position.

The combination head lamp and fog light for automobiles, in accordance with this invention is used in combination with a standard automobile head lamp ID. This head lamp consists of the usual housing containing the usual reflector |2 and enclosed by the usual lens I3. The usual clear glass bulb I4 of single or multi-fllament is mounted upon the reflector l2. The invention now departs from standard construction in that the head lamp is also provided with a frosted amber bulb l5 for a fog light which may be alternatively used with the clear bulb l4 when desired. The details of the electrical wiring necessary to switch from the lamp M to the lamp It will not be given in this specification as the circuit would be obvious to any one skilled in the art, and the circuit itself forms no part of the invention.

In Figs. 2 and 3 a modified form of the invention has been disclosed which distinguishes from the prior form in a construction by which the amber frosted .bulb is mounted in a different manner in the head lamp. In accordance with this form of the invention the reflector I2 has a small opening It at its rear end. An adjustable lamp support I1 is mounted within the housing H and is located directly behind the reflector l2. The clear glass bulb I4 is mounted on the lamp support I! and extends through the opening IS. A small reflector I8 is mounted around the socket for the lamp M and fits into and closes the opening I6 of the reflector I2.

The amber colored bulb I5 is also mounted on the lamp support I1, but normally is located between the back of the reflector l2 and the housing The socket of the amber frosted bulb |5 is provided with a reflector l8 adapted to engage across the opening l6 of the reflector l2.

The lamp support H has a head portion 20 upon which the socket for the lamps l4 and I5 are mounted, and a stem portion 2| which extends out through the housing l. The external end of the stem portion 2| is provided with a knob 22 by which it may be moved. A spring 23 is coaxially mounted on the stem 2| and normally urges the head portion 20 forwards. This spring 23 holds the reflector l8 in position across the opening I6.

The head lamp, as illustrated in Fig. 2, is now capable of acting in the usual way. To convert it to a fog lamp it is merely necessary to pull the knob 22 outwards so as to disengage the lamp M from the rear of the reflector I2, then turn the knob 22 through and then allow the spring 23 to move the lamp support forwards so that the amber frosted bulb I5 is now located through the opening I6 of the reflector l2. Fig. 3 shows the parts in this latter condition. The head lamp is now capable of acting as a fog light.

It is to be understood that instead of frosted amber, yellow, or any other shade or color bulb may be used. The bulb may be'of any desired size.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:

l. A combination headlight and fog light for automobiles having a reflector with an open back and a pair of spaced small reflectors one having a clear glass bulb and the other having an amber bulb, a support connecting said reflectors together in a position in which one small reflector closes the open back of said reflector with its respective bulb extended into the interior of said reflector with the other small reflector being disposed to one side of said reflector, a fixedly mounted tube, a stem slidably and rotatively extended through said tube and having one of its ends connected to said support intermediate of its ends, and resilient means urging said stem and support into a position in which said first mentioned small reflector will maintain its position across the open back end of said reflector, whereby said stem may be pulled against the action of said resilient means to move said small reflector away from said reflector and withdraw said bulb from the interior of said reflector so that said stem and support may be rotated relative to said reflector to align the other small reflector and its respective bulb with the open back of said reflector.

2. A combination headlight and fog light for automobiles having a reflector with an open back and a pair of spaced small reflectors one having a clear glass bulb and the other having an amber bulb, a support connecting said reflectors together in a position in which one small reflector closes the open back of said reflector with its respective bulb extended into the interior of said reflector with the other small reflector being disposed to one side of said reflector, a fixedly mounted tube, a stem slidably and rotatively extended through said tube and having one of its ends connected to said support intermediate of its ends, and resilient means urging said stem and support into a position in which said first mentioned small reflector will maintain its position across the open back end of said reflector, whereby said stem may be pulled against the action of said resilient means to move said small reflector away from said reflector and withdraw said bulb from the interior of said reflector so that said stem and support may be rotated relative to said reflector to align the other small reflector and its respective bulb with the open back of said reflector, said resilient means, comprising an expansion spring mounted coaxially on said stem and operating between adjacent portions of said support and said tube.

3. A combination headlight and fog light for automobiles having a reflector with an open back and a pair of spaced small reflectors one having a clear glass bulb and the other having an amber bulb, a support connecting said reflectors together in a position in which one small reflector closes the open back of said reflector with its respective bulb extended into the interior of said reflector with the other small reflector being disposed to one side of said reflector, a fixedly mounted tube, a stem slidably and rotatively extended through said tube and having one of its ends connected to said support intermediate of its ends, and resilient means urging said stem and support into a position in which said first mentioned small reflector will maintain its position across the open back end of said reflector, whereby said stem may be pulled against the action of said resilient means to move said small reflector away from said reflector and withdraw said bulb from the interior of said reflector so that said stem and support may be rotated relative to said reflector to align the other small reflector and its respective bulb with the open back of said reflector, and a knob mounted on the free end of said stem to facilitate the pulling and rotation of said stem.
